Back in the 1985 apart from the time travelling Delorean there were some other great technical events.
On of them was a test with mobile telephones for 200 people. This phone was not just for calling but also had Viditel which was a precursor of the internet and would let you call into information pages.
(there already were car phones and fake car phones for people who wanted to impress others).
The presenter is an astronomer who became quite famous in the Netherlands. Well have fun I am not sure if these are still in the shops?
